DEVICE FOR MIXING NATURAL GAS AND COLD AllR.

SPECIFICATION forming part of Letters Patent No. 330,932, dated November24, 1885.

Application filed September 26, 1885. Serial No. 178,241. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN H. SHEFFLER, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and use' ful device for mixing naturalgas and cold air by counteraction in a blast-pipe for heating purposes,for heating, welding, puddling, or other furnaces, of which thefollowing is a specification.

The object of myimproved device is to create or produce a greater ormore effective and cheaper heat for furnaces than that obtained by theuse of coal or other similar fuel.

It consists, essentially,in a drum to which a blast-pipe is connected atone side and gas pipe at the other side passing through the drum andinto the blastpipe, the said gaspipe being covered by a cap, and theupper end in the blast-pipe being perforated. The blast, being ofgreater force than the pressure of the gas, forces the gas back throughthe blast-pipe and drum into the furnace, the counteraction thoroughlymixing the natural gas and cold air before entering the furnace.

I obtain these results bythe mechanism illustrated in the accompanyingdrawings, in which- Figure 1 represents a top sectional view of mydevice, and Fig. 2 a side view of the 30 same.

a a is a drum with a funnel-shaped end, I), connected with the tube 0,which enters in the furnace 1 and admits the blast therein. The gasenters the pipe 9 e e 6, being regulated by the valve 9, of any ordinaryconstruction, and passes through the drum aainto the blast-pipe f f, thegas passing through the perforations i 2' in the gas-pipe e e e e andmingles with the cold air, which passes into the drum a a and 0 throughthe funnel-shaped end I) and pipe 0 into the furnace d.

What I claim as my invention, and desire to secure by Letters Patent, isas follows:

The perforated gas -pipe 6 e e e passing 5 through the drum or a, andbeing perforated at t 'i, as described, in combination with the drum a aand blast-pipe ff and valve 9, constructed as described, for thepurposes set forth.

JOHN H. SHEFFLER.
